Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 2006
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: Japan Fire Service Act; Category III test
- GLP compliance:
- no
- Key result
- Test procedure:
- ignition time on contact with air
- Temp.:
- 23 °C
- Relative air humidity (%):
- 57
- Remarks on result:
- no ignition within 5 minutes
- Remarks:
- On the paper filter
- Key result
- Test procedure:
- ignition time on contact with air
- Temp.:
- 23 °C
- Relative air humidity (%):
- 57
- Remarks on result:
- other: During dropping the samples, sparks were observed twice in the three trials, but after dropping on the stone board, the burning was not lasted.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- On exposure this substance to air, this substance decomposes to liberate hydrogen chloride.
When this substance was poured from circa 1 m height onto a non-conbustible surface, spark was observed only during dropping, but on the non-combustible surface only white smoke (hydrogen chloride) was observed. Burning on the surface was not observed within 5 miniutes. - Executive summary:
This substance gave spark only during dropping from 1 m height onto a non-combustible surface. On the surface, only liberation of white gas (hydrogen chloride) was observed. No burning was observed anymore.
We come to conclusion that this substance is not classified as pyrophoric substance.

Remarks |
When samples were setting on the filter paper, samples gave white smoke and caused char on the part of filter paper with all three testing. With Dropping testing, samples gave off white smokes in all case and at the first and third testing, sparks were observed during dropping. |
Description of key information
This substance gave spark only during dropping from 1 m height onto a non-combustible surface. On the surface, only liberation of white gas (hydrogen chloride) was observed. No burning was observed anymore.
We come to conclusion that this substance is not classified as pyrophoric substance.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
This substance reacts with oxygen and water/moisture in the air to decompose to hydrogen chloride, titanium oxide and aluminum oxide.
The liberated hydrogen chloride immediately extinguishes fire evenif this substance ignites spontaneously.
Justification for classification or non-classification
This substance inites only during dropping from 1 m height onto a non-combustible board.
But settling on the board, because of hydrogen chloride generation by decomposition, burning didn't last anymore.
